Lily plant named Ventoux

ABSTRACT

A new and distinct lily plant named Ventoux, characterized by its large flowers, bicolored petals having a white main color and an intense red-purple base color which is more heavily infused in the three outer petals, long stems, vigorous growth habit, petal tips which bend downward, and its floriferous habit.

The present invention comprises a new and distinct cultivar of lily,botanically known as Lilium, commercially known as Lilium asiatichybrid, and hereinafter referred to by the cultivar name Ventoux. Theparents were asiatic varieties belonging to division I described in"Classification of Lily Cultivars into Divisions" published by VictoriaMathews, The Royal Botanic Gardens, Kew (1989).

The new cultivar is a product of a planned breeding program which hadthe primary objectives of creating new lily cultivars with attractivecontrasting bicolor flowers and other charcteristics desired for cutflower production.

The new cultivar was originated from a hybridization made by theinventor in a controlled breeding program in Rijnsburg, The Netherlandsin 1984. Both the male and female parents were unnamed seedlings.

The new cultivar was discovered and selected as one flowering plantwithin the progeny of the stated cross by the inventor in June 1984 in acontrolled environment in Rijnsburg, The Netherlands.

The first act of asexual reproduction of the new cultivar wasaccomplished by the inventor when scales were taken from the initialselection in 1987 in a controlled environment in Rijnsburg, TheNetherlands.

Horticultural examination of selected units has demonstrated that thecombination of characteristics as herein disclosed for the new cultivarare firmly fixed and are retained through successive generations ofasexual reproduction.

The new cultivar has not been observed under all possible environmentalconditions. The phenotype may vary significantly with variations inenvironment such as temperature, light intensity, and day length,without, however, any variation in genotype. The following observations,measurements and comparisons describe plants grown in Wageningen andRijnsburg, The Netherlands under greenhouse conditions which approximatethose generally used in commercial practice.

The following traits have been repeatedly observed and are determined tobe basic characteristics of the new cultivar which in combinationdistinguish this lily as a new and distinct cultivar.

1. Large flowers.

2. Floriferous habit.

3. Bicolored flower petals comprised of a white main color and anattractive red-purple base, with the red-purple being infused moreheavily in the bottom or outer flowers. There are relatively few spotsor markings which are similar in color to the red-purple base.

4. Long flower stems.

5. The petal tips reflex downwardly.

6. Vigorous growth habit.

Of the many commercial cultivars known to the present inventor, the mostsimilar in comparison to the new cultivar is Geneve, disclosed in myU.S. Plant Pat. No. 7,101. In comparison to Geneve, the new cultivar haslarger flowers, a richer more intense red-purple contrasting color, andfewer spots on the flower petals. When flowering is forced under naturallight, Ventoux produces an inflorescence approximately 36 days earlierthan Stargazer, under the same growing conditions. Ventoux is fertile.

The accompanying photographic drawing shows typical flowercharacteristics of the new cultivar, with colors being as true aspossible with illustrations of this type. The photograph comprises a topperspective view showing several flowers open and buds at variousstages.

In the following description, color references are made to The RoyalHorticultural Society (RHS) Color Chart. The color values weredetermined at Wageningen in 1988-1989 and Rijnsburg in July 1991.
